B.20.1 The enclosure of a battery-operated appliance incorporating
an integral battery that uses metal-ion chemistry shall withstand
the pressure generated when a cell vents during failure.
Compliance is checked by inspection after the tests of Clause 19
for batteries with a capacity less than 0,2 Ah, and measurement in
the case of a) or by the test of b).
a) The total area of the unobstructed openings in the enclosure
allowing gasses to pass shall be not less than the value specified
in Table B.2; or
b) a volume of air of the amount specified in Table B.3 shall be
injected through a (2,85 ± 0,05) mm diameter orifice into the
enclosure at an initial overpressure of 2070 kPa ± 10 %. Test
fittings used for the test shall not increase the enclosure volume
by more than 3 ml. The overpressure within the enclosure shall drop
